Police say the group started hiking on the nine miles of coal company owned property around 4:30 Wednesday afternoon.

The one who fell broke his ankle. Hadesty says as the teen's friends went to help they soon realized there was no escape.

"They tried to get up here but the juvenile with the injured ankle could not make it up this bank," Hadesty told us at the site.

A cell phone became the boys life line. Rescue crews repelled down to save the teens several hours later.

The reason why this terrain is so dangerous is because it's very uneven, slick and very steep.

Despite signs saying no trespassing and a topography filled with open pits and abandoned mine shafts, Coaldale's police chief says hiking, ATV and dirt bike riding is common on the 8,000 acre property.

"This is the second time in at least two years where we had somebody go over the side," Chief Tim Delaney said.

Hadesty hopes local school districts will do a better job in informing students about the hazards of coal country.

"It would be a good start because it is dangerous," Hadesty said.

The teens are expected to be okay but were issued trespassing citations.
